Century of Inventions, 


(First Published in'l663.) 






Copyright secured, 1887, by John Phin. 


Our object in reprinting the famous " CEKTUBY OF IN- 
VENTIONS," as it is generally called, is not to give any novel 
solutions of the problems which it sets forth, but simply to 
place this famous and exceedingly interesting production 
within the reach of ordinary book-buyers. Although it has 
been several times reprinted, it is so scarce that copies are 
to be had only with considerable difficulty. Of the first 
edition, published in 1663, very few copies are to be found 
outside the shelves of a few well-known public libraries. 
It is said that this is largely due to the fact that all the 
copies that were procurable were bought up and burned by 
a rival inventor (Savary), who claimed to be the first in- 
ventor of the steam engine, Of subsequent reprints it will 
be found on inquiry that they have been so much sought 
after and read that they have been literally "thumbed 
out of existence," as the genial author of "The Book 
Hunter " expresses it in regard to similarly popular books. 

Under these circumstances it is to be hoped that our 
present offering will prove acceptable to a large number of 
those who are interested in the history of inventions and of

Edward Somerset alias Plantagenet,* Second Marqu'u jf 
Worcester, like many of the Avisest and best of this eartf 
nay, like the wisest and best bore on his escutcheon Jie 
Baston Sinister. He was descended from John of Gau it, 
Duke of Lancaster, son of Edward the Third. Charles, the 
natural son of Henry Beaufort, third Duke of Somerset, in 
that line, assumed the surname of Somerset, and from him 
was descended the famous author of " The Century of In- 
ventions," who was the eldest son of Henry Lord Herbert 
and Anne, sole daughter and heir of John Lord Russell, eld- 
est son of Francis Russell, Earl of Bedford. He was born

early in 1601 the exact date 'being unknown. During his 
father's life-time he was known first as Lord Herbert, and 
afterwards as Earl of Glamorgan. On the death of his 
father he succeeded to the titles of Earl and Marquis of 

His education appears to have been conducted privately 
under the tutorship of a Mr. Adams. It does not appear 
that he was entered at any of the great English colleges, 
though it is possible that he may have been connected with 
some foreign university. Be this as it may, it is quite cer- 
tain that his education was as complete and thorough as 
that of any young man of his time. 

In the year 1628 he married Elizabeth, daughter of Sir 
William Dormer. She bore him one son and two daughters. 
The son, Henry Somerset, was created first Duke of Beau- 

It is supposed that shortly after his marriage he retired to 
Raglan Castle and devoted himself to study and experiment, 
but of this we have no record. 

In the year 1635 (May 3151) he lost his wife, to whom he 
was greatly attached. Four years later he married Mar- 
garet, second daughter of Henry O'Brien, Earl of Thomond. 
He obtained by his second wife some valuable possessions, 
and he also became connected with some of the most 
wealthy and powerful families in Ireland. By his second 
wife he had one daughter who died while quite young. 

It is an unfortunate circumstance that we know very little 
of the daily life of the Marquis at this period, and nothing at 


all of his pursuits, studies and inventions, except in a most 
general way. Even the exact dates of important events in 
his life are unknown, and the length of time during which 
he was imprisoned in the Tower is a matter of conjecture. 
That he continued his scientific and mechanical pursuits even 
during the early tumults of the civil war is pretty certain, 
and that some of his inventions were put in operation, at 
Raglan Castle, on a scale of considerable magnitude, seems 
more than probable from the following anecdote related by 
Dr. Bayly : "At the beginning of this Parliament (Nov. 1640) 
there were certain rustics who came into Raglan Castle to 
search for arms, his lordship* being a Papist. The Marquis 
met them at the castle gate, desiring to know whether they 
came to take away his money, seeing they intended to dis- 
arm him. They stated that they made the application merely 
in consequence of his being a recusant. To which he re- 
plied, ' He was a peer of the realm, and no convict recusant, 
therefore the law could not in reason take notice of any such 
things.' Finding some sharp and dubious expressions com- 
ing from the Marquis, they were at last willing to take his 
word ; but he, not willing to part with them on such easy 
terms, had before resolved to return them one fright for an- 
other. With that view he conveyed them up and down the 
castle, until at length he brought them over a high bridge 
that arched over the moat that was between the castle and 
the great tower, wherein the Lord Herbert had newly con- 

* The father of the famous Marquis. 


trived certain water-works, which, when the several engines 
and wheels were to be set a-going, much quantity of water, 
through the hollow conveyances of the aqueducts, was to be 
letdown from the top of the high tower; which, upon the 
first entrance of these wonderful asinegoes, the Marquis had 
given order that these cataracts should begin to fall, which 
made such a fearful and hideous noise, by reason of the hol- 
lowness of the tower, and neighboring echoes of the castle, 
and the waters that were between, and round about, that 
there was such a roaring as if ihe mouth of hell had been 
wide open, and all the devils conjured up, occasioning the 
poor silly men to stand so amazed as if they had been half 
dead ; and yet they saw nothing. At last, as the plot was 
laid, up came a man staring and running, crying out ' Look 
to yourselves my masters, for the lions are got loose? Where- 
upon the searchers tumbled so over one another escaping 
down the stairs, that it was thought one half of them would 
break their necks, never looking behind them until out of 
sight of the castle." 

Troublous times were now approaching. Charles the First 
was in sore need of money, and Lord Herbert and his father 
advanced him large loans from their personal estate. In 
addition to this they raised and sustained a considerable 
body of troops. Up to this time the highest dignity at- 
tained by the family was that of Earl of Worcester. On the 
2nd of November, 1642, Henry, (the father of the famous 
Edward) was created Marquis of Worcester. The civil war 
now raged, and Raglan Castle was garrisoned by troops 


maintained by the Somersets in the interest of the King. 
The scientific and mechanical skill of Lord Herbert, (the fu- 
ture Marquis) were here brought into play, and a powder 
mill was erected on the estate and actively operated for the 
supply of ammunition to the royal troops. 

As a military man, however, Lord Herbert does not seem 
to have achieved much success. His troops were defeated 
by the Parliamentary forces, and his pecuniary losses were so 
enormous that he was made a poor man for the rest of his 

In 1645 he was sent to Ireland by the King with a commis- 
sion to raise a body of 10,000 Irish troops for service in Eng- 
land to oppose the parliamentary forces. To secure the aid of 
the Catholics in this effort, Lord Herbert, recently created Earl 
of Glamorgan, was empowered to offer the Romish dignita- 
ries the most liberal terms, not only as regarded toleration, 
but in the matter of lands, titles, etc., to be placed in their 
possession. This arrangement was, however, completely up- 
set by certain wholly unlocked for events. The Popish 
Archbishop of Tuam, President of Connaught, and one of 
the Supreme Council at Kilkenny, going into Ulster to visit 
his diocese, and put into execution an order for arrears of 
his Bishopric, granted to him by that Council, met with a 
body of Irish troops marching to besiege Sligo, and joined 
with them. When they came near that town, the garrison 
made a sally on the iyth of October, charged the troops, and 
utterly routed them, killing the Archbishop in the en- 
counter. Amongst the baggage of the Archbishop was 


found an authentic copy, attested and signed by several 
bishops, of the treaty concluded with them by the Earl of 
Glamorgan. The result of this disclosure was that Lord 
Digby charged the Earl with suspicion of high treason, and 
moved that his person be secured. The charge being fully 
substantiated, the Earl was committed to the custody of the 
Constable of Dublin Castle in the condition of a close 
prisoner. After a brief confinement he was liberated on 
bail, but under the condition that he should not leave the 
Kingdom of Ireland. 

Meanwhile Raglan Castle, the family seat and the scene 
of his early studies and experiments, was taken by General 
Fairfax after a prolonged seige. The letters and papers 
were carried off and the castle ordered to be demolished. 
It is probable that in the dispersion and destruction of 
these papers we have lost the records of many of the early 
experiments and inventions made by the Marquis. 

These accumulated misfortunes no doubt hastened the 
death of his father, which occurred in December, 1646. 

Very soon after these events matters were so arranged 
that he was enabled to go to France, where he remained in 
exile for four or five years. That some arrangement look- 
ing to his voluntary exile was made with the government 
is more than probable, as the Marquis was too honorable to 
leave in the lurch his friends, the Marquis of Clanricarde 
and the Earl of Kildare, who were on his bond for ten 
thousand pounds each. 

On the 3oth of January, 1649, Charles the First was exe- 


cuted; the commonwealth was established on the 6th of 
February following, and the Protectorate under Cromwell in 
1654. Meanwhile Charles the Second had escaped to the 
continent and set up a migratory court. Although the 
Marquis was not a constant attendant at this court, he ap- 
pears to have been in communication with them, and in 
1652 he was sent to England for private intelligence as well 
as for supplies. Unfortunately, however, he was recognized, 
made prisoner, and committed to the tower, where he re- 
mained for a period variously estimated at from two to six 
years. During his confinement he wrote the famous book 
known as " A Century of Inventions," which, however, was 
not published until 1663, though it was supposed that sev- 
eral manuscript copies were made and circulated amongst 
his friends. One of these is now in the British Museum, and 
is interesting on account of certain slight variations from 
the printed book. 

In 1660 Charles the Second returned to England and was 
placed upon the throne of his fathers. One would suppose 
that a man who had suffered so much in attestation of his 
loyalty would have been most liberally treated, but we find 
that, although the estates of the Marquis were restored, they 
were heavily encumbered and greatly despoiled. The tim- 
ber had been removed, the buildings were in ruins, and the 
sources of income were but trifling. He therefore took up 
his residence in London, where, in the hopes of retrieving 
his fortune, he devoted himself to the prosecution of his studies 


and the perfecting of his inventions, though it would seem 
without any very marked financial success. 

Four years after the publication of the " Century " on 
the 3rd of April, 1667 he died in London, and on the igth 
of the same month he was buried in the family vault within 
the Parish Church of Raglan. 

Such is a meagre outline of the life of the Marquis of 
Worcester. Those who desire to follow out the details of 
his political relations more closely will find much material 
in the Life by Henry Dircks a crude and ill-digested per- 
formance, which should be called a collection of materials 
for a biography, rather than a biography. 

That the Marquis of Worcester was a keen student and 
an enthusiastic inventor, there can be no doubt. That the 
results which he attained have been greatly over-estimated is 
very certain, but the wonder is that he should have accom- 
plished anything at all when we consider the troublous times 
in which his lot was cast. 

As a man he was loyal, brave and honest, qualities not 
always found in high places in those days. Unfortunately, 
for himself, he was, during a great part of his life, attached 
to the losing side, and when the tide of success turned he 
was too old to secure the favor of such a frivolous and sen- 
sual monarch as Charles the Second. 


If we except those who have taken an active controver- 
sial part in religion or politics there is no man in regard to 
whom such positively opposite opinions have been enter- 
tained, as the Marquis of Worcester. Dircks, in the Dedi- 
cation prefixed to his Life of the Marquis, affirms that it 
would be "impossible to name his compeer either amongst 
the highest nobility or the most eminent scientific celebrities 
of Europe, during the last two centuries." In other words, 
Newton, Davy, Faraday, Watt, Stephenson, and all the other 
stars in the bright galaxy which stretches across the last two 
two hundred years, pale before the effulgence of the fame 
of the Marquis of Worcester ! ! On the other hand Walpole 
speaks of the "Century of Inventions" as "an amazing 
piece of folly," and rates the author as little better than a 
madman ! It is pretty certain that the truth lies between 
these two extremes, for the one is the conclusion of a man 
of trinkets and trifles who never in his life grappled with a 
serious subject and conquered it, and the other is the out- 
come of mere toadyism on the part of a man Avho evidently 
wished to ingratiate himself with certain aristocratic fami- 

Unfortunately, for the Marquis, the labors of Mr. Dircks 


have rendered certain the fact tljat to him we owe absolutely 
nothing so for as inventive progress is concerned. He may 
have constructed steam engines more perfect than those 
turned out by the best factories of the present day; he 
may have perfected inventions, which, if now understood, 
would render both telegraph and telephone useless, and his 
"Water-Commanding Engine" may have been not only 
" Semi-omnipotent " but actually omnipotent, and yet it is no 
injustice to him and no ingratitude on our part for us to say 
that we owe him NOTHING, for with all the efforts of Mr. 
Dircks and all the facilities placed at his command, as re- 
gards old papers, records, models, etc., there has not been 
brought to light one scrap of writing, or one fragment of a 
model, that tends to show that the Marquis ever developed a 
successful invention or that he ever carried one to such a de- 
gree of completion as would enable a modern mechanic to 
profit to any extent by his labors. 

It is therefore very obvious that we owe none of our me- 
chanical or inventive progress to him. Whether he actually 
succeeded in perfecting the inventions that he describes, and 
especially, whether or not he was the real inventor of the 
steam engine, are questions which will be attacked by those 
who desire to gratify their antiquarian curiosity, but not by 
those who desire to render to the name of a benefactor the 
homage which gratitude prompts. 

Many of the inventions described by the Marquis are frivo- 
lous and useless. He gives no clue to his ciphers, but it is 
the simplest of all tasks to devise methods which will con- 


form to all the conditions stated in his book ; the only diffi- 
culty is that in these days the deciphering of cryptographs 
has made such progress that any such ciphers would be use- 
less. A mere tyro in the art would be able to decipher 
them and in a few minutes force them to give up their true 

That many of the alleged inventions described in the 
Century were solved only in the imagination of the Marquis 
can hardly be doubted by any intelligent student. For ex- 
ample, No. 56 is a very perfect description of a common form 
of so-called perpetual motion that is to say, it is one of 
those forms which are almost certain to occur to every active 
mechanical mind that attempts to solve this famous problem. 
We have known it to be invented a dozen times by persons 
whose efforts and ideas were entirely independent of each 
other, and who had never heard of the thing before. We have 
had models of this contrivance brought to us, and so strong 
was the hold that the theoretical idea had taken upon the 
minds of the inventors that although in every case the 
models failed to operate yet this was invariably attributed to 
the mechanical defects and rude workmanship of the model 
and not to any fallacy lurking in the theory. And every edi- 
tor of a popular scientific journal and every person having 
much to do with inventors, will no doubt testify to the same 

It is a fact well known to all who are actually brought 
into contact with mechanical progress that the inventive 
world is full of embryo inventions whose maturity is an im- 


possibility. At one time our. Patent Office required models 
of all inventions capable of being so illustrated. As a gen- 
eral rule the office accepted what were called "dummy" 
models that is to say, models that merely showed the form 
and arrangement of the parts without actually working. In 
particular cases the office had the power to demand " work- 
ing " models, but these were not often required. Now every 
patent agent will testify that the percentage of inventions 
which seemed f. asible in drawings and dummy models and 
yet failed in actual practice was very large. And, so plau- 
sible did these schemes seem that the authors would have 
had no hesitation in risking their lives on the results; far less 
would they have hesitated to describe them as " inventions 
which they had tried and perfected." So that we are far 
from impugning the veracity of the Marquis when we say 
that many of these things existed only in his imagination, for 
it must be borne in mind that every inventor is gifted with a 
vivid imagination ; indeed, if defective in this respect, he 
never could be an inventor. 

Those who will carefully study the inventions described in 
the " Century " will be surprised to see how many of them 
have been brought to a degree of perfection of which the 
Marquis could have had no idea. Not only has the 
power of steam been so developed that the claims of the 
Marquis have been far exceeded, but our telegraphs, tele- 
phones, armored ships, land turrets and other contrivances 
throw far in the shade anything ever conceived or named 
by him. But, when we read his wonderful descriptions we 


cannot but accord to him a power of vision far in advance of 
his day. He had a marvellous insight into the future, and 
unbounded faith in the possibilities of science and mechanics, 
and the probability is that if he had closely settled down to 
the hard work of thorough investigation, and the prosaic 
study of facts and principles, he would have been the real inven- 
tor of the modern steam engine. But not only did he fall 
upon evil times, his mind was too enthusiastic and flighty for 
such work, and he spread over a " Century " of inventions 
that power which he ought to have confined to one or two. 

Amongst the questions which always occur when the name 
of the Marquis of Worcester is brought forward, are those re- 
lating to the invention of the steam engine. Prof. Robi- 
son and some others broadly claim that he was the inven- 
tor of this modern aid to civilization, Avhile Arago claims the 
like for De Caus, others claim it for Savery, and the friends 
of other inventors make like claims. The thoughtful student 
will see that none of these claims are well founded. The 
development of the Steam Engine was a gradual process, pro- 
ceeding in some cases along distinct and unconnected lines, 
which in every case served to develop some useful princi- 
ple, but which did not always produce a practical result, 
capable of utilization in the modern machine. 

The principal stages of this course of invention seem to 
have been the following : 

1. The discovery of the expansive force of steam. 

2. Its direct application to the production of mechanical 


3. Its direct application to the raising of water in closed 

4. Its use in the formation of a vacuum so as to produce 
mechanical motion. 

5. Its application to the direct movement of a piston in 
both directions. 

At every one of these stages various minor improvements 
were made, any one of which would, if not superseded by 
better, have made the fame and fortune of any inventor, but to 
no one inventor do we owe our advancement through more 
than one stage. Let us briefly glance at these several 

The expansive power of steam was no doubt discovered 
at a very early period in the history of man's progress. In- 
deed, it is quite certain that it antedates many of our well- 
defined historic periods, such as the bronze and iron ages. 
It was probably discovered as soon as men had constructed 
rude vessels of earthen ware in which they could cook their 
food. The lids of these vessels would often be raised by 
steam ; explosions of pent-up vapor would occur, and even 
in the infancy of the arts, men would be taught to respect 
the tremendous power which now does us such noble ser- 

We can easily imagine the consternation of the ancients at 
some of these tremendous manifestations, and we can easily 
suppose that they would be attributed to the working of 
some Genie or Spirit, for all the invisible forces were so re- 
garded by men in early times. Our modern word gas ig 


nothing but the word ghost in a different form, and it came 
to be applied to invisible airs, because these were supposed 
to be subterranean spirits. So the name of the metal Cobalt 
is merely a transformation of the word Kobold, the name of 
an evil spirit who was supposed to haunt mines, and change 
good metal to worthless alloy. In the hands of the ancient 
priests, steam played an important part in many Pagan 
ceremonies, and therefore we may safely conclude that this 
stage of the discovery of steam as a source of power ante- 
dates all history. 

The same is true of the second stage. In his work en- 
titled" Spiritalia," Hero, of Alexandria, describes three modes 
in which steam might be employed as a mechanical power : 
i, to raise water by its elasticity; 2, to elevate a weight by 
its expansive force, and 3, to produce a rotary motion by its 
reaction in escaping from the side of a tube. The latter 
works on the same principle that operates the well-known 
Barker's water-mill. Hero does not claim these inventions 
as his own, but, as has been well said, " though posterity is 
really not indebted to him for the invention, it is still more 
beholden to him for the bequest of his description, than if 
he had been the inventor and had omitted to describe it." 
The invention of Branca, and also the well known modifica- 
tion of Branca's device, in which a jet of steam is made to 
act directly on the buckets or vanes of a breast-wheel, come 
under this head. 

In the third stage we find steam used in close vessels and 
pressing directly upon the water to be raised. This was a 


direct step in advance, though in some of Its forms it was 
no doubt invented at a very early period. The crudest 
form of the device is that of which the so-called engine of 
De Caus is an illustration. In this " engine " the entire body 
of water to be raised must first be heated above the boil- / 
ing point an arrangement which is utterly impracticable so \ 
far as any useful mechanical purpose is concerned. This de- 
vice is, however, very old much older than De Caus. 

It would of course soon be found that it was not neces- 
sary to heat the water to be raised ; that steam from a separ- 
ate boiler would be much more economical. This method 
was fully described by Porta in 1601, and is still in use in 
a simple and tolerably efficient form of water-raising engine. 

The fact that when steam is condensed by cold, a 
vacuum is formed, was well known in very ancient times. 
The old steam blowers or Eolipiles were frequently filled by 
utilizing this principle, and it was not a great step from the 
mere raising of water into an Eolipile to the raising of a 
weight by the use of a piston. Pistons for raising water an- 
tedate any recorded form of the steam engine, and their 
adaptation to the production of mechanical movements by 
the pressure of the atmosphere, did not require any great 
stretch of the inventive faculty. 

The fifth stage in which steam was caused to act directly on 
a piston, was the culmination of the invention of the steam en- 
gine. An infinite number of modifications, and of additional 
devices and improvements may have been added, but this was 
the fundamental idea the adoption of which brought success. 


To which of these stages the inventions of the Marquis be- 
longed we have no means of knowing. There is not a 
scrap of drawing, a fragment of a model, or an intelligible 
description remaining to aid us on this point. True, we 
have many sketches, and so-called restorations, but they are 
all the products of the fancy and the inventive powers of 
biographers and commentators. 

As regards the engine at Vauxhall, it may, for aught we 
know, have been a mere pump. Two very intelligent travellers 
visited the works at times considerably apart, and both speak 
of the use of horses for driving the engines. A steam en- 
gine, worked by horses, is certainly a curious invention. 

Historians have indulged in much speculation as to the 
causes which delayed the invention of the steam engine to so 
late a period. It is acknowledged on all hands that the pro- 
perties and powers of steam were tolerably well understood, 
and all the mechanical elements of a successful engine had 
been invented the crank, the piston, etc. And the 
mechanical skill of the ancients has furnished a subject for 
many a lecturer on the " lost arts." Why then was not the 
steam engine produced ? Simply because it was not needed. 
What would have been the use of a motive power to a peo- 
ple who had no machinery for it to drive ? The Greeks and 
Romans had not even a threshing machine, far less spinning 
machinery, power looms, or rolling mills. All their mechan- 
ical work was done by hand-power, and so long as the 
spinning wheel was turned by women and the shuttle driven 
by men, of what use could a steam engine have been to them ? 


In the history of the arts., and sciences we find that the 
progress of each depends greatly upon that of the others. 
Astronomy and physiology came to a standstill until the 
science and practice of optics were so improved as to place 
the telescope, the spectroscope and the microscope at their 
command. Since then the progress made in these depart- 
ments has been simply marvellous. In the arts we find that 
every new demand gives rise to new inventions and new dis- 
coveries. As soon as the English mines required power of 
some kind to keep them free from water, pumps suited to 
the purpose were invented. At first these pumps were 
worked by hand, but as soon as greater power became ne- 
cessary new inventions were made and horse-power was ap- 
plied. This enabled the mines to be carried to a greater 
depth, and then a still more powerful motor was needed, and 
as soon as this became apparent the steam engine was in- 

In the arts as in daily life, the extent of our wants is the 
measure of our civilization. 


In the following pages we give a verbatim reprint of the 
Edition of 1663 the only one known to have been pub- 
lished during the life of the Marquis. 

There is in the British Museum (Harleian MS. No. 2428) 
a manuscript copy of the Century. Partington affirms 
that this copy is in the handwriting of the Marquis, 
but such is not the case. It is evidently a mere copy made 
by some one for his own convenience before the work was 
printed. The top of the title page of the MS. copy bears the 
words "from August ye 291!! to Sept. ye 2ist, 1659" This 
is supposed to indicate the time occupied in copying it. 

The MS. copy differs in several places from the printed 
edition. These variations we have given in foot notes, so 
that the reader may have the exact text of both the printed 
and the written copy. 

In the MS. copy, however, No. 88 instead of being a de- 
scription of a Brazen Head, is a description of "A Stamping 
Engine" for coining money. The description is as fol- 
lows: " An engine without ye least noyse, knock or use of 
fyre, to coyne and stamp 100 Ib. in an houre by one man."

Be not startled if I address to all, and every of you, this 
Century of Summary Heads of wonderful things, even after 
the Dedication of them to His most Excellent Majesty, since 
it is with His most gracious and particular consent, as well 
as indeed no wayes derogating from my duty to His Sacred 
Self, but rather in further order unto it, since your Lordships, 
who are his great Council, and you, Gentlemen, His whole 
Kingdom's Representatives (most worthily welcome unto 
Him,) may fitly receive into your wise and serious considera- 
tions what doth or may publickly concern both His Majesty 
and His tenderly-beloved People. 

Pardon me if I say (my Lords and Gentlemen) that it is 
joyntly your parts to digest to His hand these ensuing par- 
ticulars, fitting them to His palate, and ordering how to re- 
duce them into practice in a way useful and beneficial both 
to His Majesty and His Kingdom. 

Neither do I esteem it less proper for me to present them 
to you, in order to His Majesty's service than it is to give 


into the hands of a faithful aud provident Steward whatso- 
ever dainties and provisions are intended for the Master's 
diet; the knowing and faithful Steward being best able to 
make use thereof to his Master's contentment and greatest 
profit, keeping for the morrow what ever should be over- 
plus or needless for the present day, or at least, to save 
something else in lieu thereof. In a word (my Lords and 
Gentlemen), I humbly conceive this Simile not improper, 
since you are His Majesty's provident Stewards, into whose 
hands I commit my self with all properties fit to obey you, 
that is to say, with a heart harbouring no ambition, but an 
endless aim to serve my King and Countrey : and if my en- 
deavors prove effectual (as I am confident they will), his 
Majesty shall not onely become rich, but his people likewise, 
as Treasurers unto Him; and His Pierless Majesty, our 
King, shall become both belov'd at home and fear'd abroad, 
deeming the riches of a king to consist in the plenty enjoyed 
by His People. 

And the way to render Him to be feared abroad is, to 
content his People at home, who then, with heart and 
hand, are ready to assist him; and whatsoever God blesseth 
me with to contribute towards the increase of His Revenues 
in any considerable way, I desire it may be employed to the 
use of His People; that is, for the taking off such Taxes or 
Burthens from them as they chiefly groane under, and by a 
Temporary necessity onely imposed upon them, which being 
thus supplied will certainly best content the King and satisfie 
His People, which I dare say is the continual Tend of all 


your indefatigable pains, and the perfect demonstrations of 
your Zele to His Majesty, and an evidence that the King- 
doms Trust is justly and deservedly reposed in you. And if 
ever Parliament acquitted themselves thereof, it is this of 
yours, composed ot most deserving and qualified Persons 
qualified, I say, with your affection to your Prince, and with 
a tenderness to His People; with a bountiful heart towards 
Him, yet a frugality in their behalfs. 

Go on, therefore, chearfully (my Lords and Gentlemen), 
and not onely our gracious King, but the King of Kings 
will reward you, the Prayers of the People will attend 
you, and His Majesty will, with thankful arms, embrace 
you. And be pleased to make use of me and my en- 
deavors to enrich them, not my self; such being my 
onely request unto you, spare me not in what your Wisdoms 
shall find me useful, who do esteem myself not onely by the 
Act of the Water-commanding Engine (which so chearfully 
you have past), sufficiently rewarded, but likewise with cour- 
age enabled to do ten times more for the future; and my 
Debts being paid, and a competency to live according to my 
Birth and Quality setled, the rest shall I dedicate to the 
service of our King and Countrey by your disposals: and es- 
teem me not the more or rather any more, by what is past, 
but what 's to come; professing really, from my heart, that 
my Intentions are to outgo the six or seven hundred thou- 
sand pounds already sacrificed, if countenanced and en- 
couraged by you, ingenuously confessing that the melancholy 
which hath lately seized me, (the cause whereof none of 


you but may easily guess,) bath, I dare say, retarded more 
advantages to the public service than modesty will permit 
me to utter: And now revived by your promising favors, I 
shall infallibly be enabled thereunto in the Experiments extant, 
and comprised under these heads practicable with my direc- 
tions by the unparall'd workman, both for trust and skill, Cas- 
per Kaltoffs hand, who has been these five-and-thirty years as 
in a school, under me imployed, and still at my disposal, in a 
place by my great expences made fit for publick service, 
yet lately like to be taken from me, and consequently from 
the service of King and Kingdom, without the least re- 
gard of above ten thousand pounds expended by me, and 
through my Zele to the Common good ; my Zele, I say, a 
field large enough for you (my Lords and Gentlemen) to 
work upon. 

The Treasures buried under these heads, both for War, 
Peace, and Pleasure, being inexhaustible ; I beseech you 
pardon me if I say so; it seems a Vanity, but compre- 
hends a Truth ; since no good Spring but becomes the more 
plentiful by how much more it is drawn, and the Spinner to 
weave his webb is never stinted but further inforc'd. 

The more then that you shall be pleased to make use of my 
Inventions, the more Inventive shall you ever find me; one 
Invention begetting still another, and more and more impro- 
ving my ability to serve my King and you ; and as to my 
heartiness therein, there needs no addition, nor to my readi- 
ness a spur. And therefore (my Lords and Gentlemen) be 
pleased to begin, and desisist not from commanding me till I 


flag in my obedience and endeavors to serve my King and 

For certainly you'lfind me breathless first Vexpire, 
Before my hands grow voeary, or my legs do tire. 

Yet, abstracting from any Interest of my own, but as a 
Fellow-Subject and Compatriot, will I ever labor in the Vine- 
yard, most heartily and readily obeying the least summons 
from you, by putting faithfully in execution what your Judg- 
ments shall, think fit to pitch upon amongst this Century of 
Experiences, perhaps dearly purchased by me, but now 
frankly and gratis offered to you. Since my heart (me- 
thinks) cannot be satisfied in serving my King and Country, 
if it should cost them anything; As I confess, when I had 
the honor to be neare so obliging a Master as His late 
Majesty, of happy memory, who never refused me his Ear to 
any reasonable motion: And as for unreasonable ones, or 
such as were not fitting for him to grant, I would rather to 
have dyed a thousand deaths than ever to have made any 
one unto him. 

Yet whatever I was so happy as to obtain for any deserving 
Person, my Pains, Breath and Interest employed therein, 
satisfied me not, unless I likewise satisfied the Fees ; but that 
was in my Golden Age. 

And even now, though my ability and means are short- 
ened, the world knows why my heart remains still the 
same ; and be you pleased, my Lords and Gentlemen, to 
rest most assured, that the very complacency that I shall 


take in the executing your 'Commands shall be unto me a 
sufficient and an abundantly-satisfactory reward. 

Vouchsafe therefore to dispose freely of me, and what- 
ever lieth in my power to perform; first, in order to His 
Majesty's service; secondly, for the good and advantage of 
the Kingdom ; thirdly, to all your satisfactions, for particular 
profit and pleasure to your individual selves, professing that 
in all and eaeh of the three respects, I will ever demean my 
self as it best becomes, 

My Lords and Gentlemen, 
Your most passionately -bent Fellow -Subject in 
His Majesty's service, Compatriot for the 
publick good and advantage, and a most 
humble servant to all and every of you. 




Names and Scantlings of 

Inventions by me already 

i. Several sorts of Seals, some shewing by scrues, others 
by gages fastening or unfastening all the marks at once ; 
others by additional points and imaginary places, propor- 
tionable to ordinary Escocheons 1 and Seals at Arms, each 
way palpably and punctually setting down (yet private from 
all others but the Owner and by his assent) the day of the 
Moneth, the day of the Week, the Moneth of the Year, the 
Year of our Lord, the names of the Witnesses, and the indi- 
vidual place where any thing was sealed, though in ten 
thousand several places, together with the very number of 
lines contained in a Contract, whereby falsification may be 
discovered and manifestly proved, being upon good grounds 

Upon any of these Seals a man may keep Accompts of 

i Escucheons. 


Receipts and disbursements, from one Farthing to an hun- 
dred millions, punctually shewing each pound, shilling, peny, 
or farthing. 

By these seals, likewise, any Letter, though written but in 
English, may be read and understood in eight several lan- 
guages, and in English itself to clean contrary and different 
sense, unknown to any but ihe Correspondent, and not to 
be read or 1 understood by him neither, if opened before it ar- 
rive unto him; so that neither Threats nor hopes of Re- 
ward can make him reveal the secret, the Letter having 
been intercepted and first opened by the Enemy. 

2. How ten thousand Persons may use these seals to all 
and every of the purposes aforesaid, and keq) their 
secrets 2 from any but whom they please. 

3. A Cypher and Character so contrived, that one line, 
without returns and 3 circumflexes, stands for each and every 
of the 24. Letters ; and as ready to be made for the one letter 
as the other. 

4. This invention refined, and so abbreviated that a point 
onely sheweth distinctly and significantly any of the 24. 
letters ; and these very points to be made with two pens, 
so that no time will be lost, but as one finger riseth 
the other may make the following letter, never clogging 
the memory with several figures for words and com-

fusion, are thus speedily and punctually, letter for letter, 
set down by naked and not multiplied points. And nothing 
can be less than a point, the Mathematical definition of 2 be- 
ing, Cujus pars nulla. And of a motion no swifter imagin- 
able then 3 Semiquavers or Releshes, yet applicable to this 
manner of writing. 

5. A way, by a Circular motion, either along a Rule or 
Ring-wise, to vary any Alphabet, even this of Points, so that 
the self-same Point, individually placed, without the least ad- 
ditional mark or variation of place, shall stand for all the 24. 
letters, and not for the same letter twice in ten sheets writ- 
ing; yet as easily and certainly read and known as if it stood 
but for one and the self-same letter constantly signified. 

6. How at a Window, far as Eye can discover 4 black 
from white, a man may hold discourse with his Correspon- 
dent without noise made or notice taken ; being, according 
to occasion given and means afforded, Ex re nata, and no 
need of Provision beforehand ; though much better if fore- 
seen, and means prepared for it, and a premeditated course 
taken by mutual consent of parties.

8. A way how to level aud shoot Cannon by night as 
well as by day, and as directly ; without a platform or meas- 
ures taken by day, yet by a plain and infallible rule. 

9. An Engine, portable in one's Pocket, which may be 
carried and fastened on the inside 1 of the greatest Ship, 
Tanquam aliud age/is, and at any appointed minute, though 
a week after, either of day or night, it shall irrecoverably 
sink that Ship. 

10. A way from a mile off to dive and fasten a like Engine 
to any Ship, so as it may punctually work the same effect 
either for time or execution. 

11. How to prevent and safeguard any Ship from such an 
attempt by day or night. 

12. A way to make a Ship not possible to be sunk, 
though shot an hundred times betwixt wind and water by 
Cannon, and should lose a whole Plank, yet in half an hours 
time, should be made as fit to sail as before. 

13. How to make such false Decks, as in a moment 
should kill and take prisoners as many as should board the 
Ship, without blowing the Decks up or destroying them, 
from being reducible, and in a quarrer of an hours time 
should recover their former shape, and to be made fit for 
any imployment without discovering the secret. 

14. How to bring a force to weigh up an Anchor, or to 
do any forcible exploit, in the narrowest or 2 lowest room in 

ithe side. 
*and -for or. 


any Ship, where few hands shall do the work of many; and 
many hands applicable to the same force, some standing, 
others sitting, and 1 by virtue of their several helps, a great 
force augmented in little room, as effectual as if there were 
sufficient space to go about with an Axle-tree, and work 
far from the Centre. 

15. A way 2 how to make a Boat work it self against 
Wind and Tide, yea both without the help o( man or 
beast; yet 3 so that the Wind or Tide, though directly 
opposite, shall force the Ship or Boat against itself," and 
in no point of the Compass, but it shall be as effectual as 
if the wind were in the Pupp, or the stream actually with 
the course it is to steer, according to which the Oars shall 
row, and necessary motions work and move towards the 
desired Port or point of the Compass. 

1 6. How to make a Sea-castle or Fortification Cannon 
proof, and capable of a thousand men, yet sailable at plea- 
sure to defend a passage; or, in and hour's time, to divide 
itself into three Ships, as fit and trimmed to sail as before : 
And even whilest it is a Fort or Castle, they shall be unani- 
mously steered, and effectually be driven by an indifferent 
strong wind.

to keep Wine in, delicate Bathing places, and the like; with 
musick made with 1 Mills, and all in the middest of the stream 
where it is most rapid. 

18. An Artificial Fountain, to be turned like an Hour- 
glass, by a child in the twinkling of an eye; it 2 holding a 
great quantity of water, and of force sufficient to make snow, 
ice, and thunder, with a 3 chirping and singing of birds, and 
shewing of several shapes and effects usual to Fountains of 

16. A little engine within a Coach, whereby a child may 
stop it, and secure all persons within it, and the Coachman

career; a child being sufficiently capable to loosen them in 
what posture soever they should have put themselves, turn- 
ing never so short, for a child can do it in the twinkling of 
an eye. 

20. How to bring up water Balance-wise, so that as 
little weight or force as will turn a Balance will be onely 
needful, more then the weight of the water within the 
Buckets, which counterpoised, 5 empty themselves one into

21. How to raise water constantly with two Buckets onely 
day and night, without any other force then its own motion, 
using not so much as any force, wheel or sucker, nor more 
pulleys than one on which the cord or chain rolleth, with a 
bucket fastened at eacli end. This I confess 1 I have seen 
and learned 2 of the great Mathematician Claudius 3 his 
studies at Rome, he having made a Present thereof unto a 
Cardinal ; and I desire not to own any other mens* inven-

24. How to increase the strength of a Spring to such a 
height as to shoot Bumbasses and Bullets of an hundred 
pound weight a Steeple height, and a quarter of a mile off 
and more, Stone-bow-wise; admirable for Fire-works, and 
astonishing of besieged Cities, when, without warning given

dred pound and yet shall take up two hundred pound,

portionally, to millions of pounds. 

26. To raise weight as 3 well and as forcibly with the draw- 
ing back of the Lever, as with the thrusting it 4 forwards ; and 
by that means to lose no time in motion or strength. This I 
saw in the Arcenal at Venice?

a most inconsiderable strength from place to place.

in a few hours time may be placed over a river half a mile 
broad, whereon with much expedition, may* be transported 
Horse, Foot and Cannon. 

29. A portable Fortification able to contain five hundred 
fighting men, and yet 3 in six hours time, may 4 be set up 
and made Cannon-proof, upon the side of a River or Pass, 
with Cannon mounted upon it, and as complete as a regular 
Fortification, with Half-moons and Counterscarps. 

30. A way in one nights time to raise a Bulwork twenty or 
thirty foot high, Cannon-proof, and Cannon mounted upon 
it, with men to over-look, command and batter a Towne; for 
though it contain but four Pieces, they shall be able to dis- 
charge two hundred Bullets each hour.

to a Castle or Town-wall, and over the very Ditch at Noon-

44. To make a Key of a Chamber door, which to your 
sight hath its Wards and Rose-pipe but Paper-thick, and yet 
at pleasure in a minute of an hour, shall become a perfect 
Pistol, capable to shoot through a Brest-plate commonly of 
Carabine-proof, with Prime, Powder and Firelock, undis- 
coverable in a strangers hand. 

45. How to light a Fire and a Candle at what hour of the

Pistol at pleasure; yet by a stranger, not knowing the secret,

Pool or Pail of water shall presently rise from the bottom, 
and constantly shew by the superficies of the water the hour 
of the day or night, never rising more out of the water then

48. A scrued Ascent, instead of Stairs, with fit landing 
places to the best Chambers of each Story, with Back-stairs 
within the Noell of it, convenient for servants to pass up and 
down to the inward Rooms of them, unseen and private. 

49. A portable Engine, in way of a Tobacco-tongs, 
whereby a man may get over a wall, or get up again being 
come down, finding the coast proving 1 unsecure unto him. 

50. A complete light portable Ladder, which taken out 
of ones Pocket, may be by himself fastened an hundred foot

duceth all things to a private correspondence, most useful for 
secret Intelligence.

Musical Instrument within hearing, in a seeming way of 
tuning it ; or of an unskilful beginner. 

53. A way how to make hollow and cover a Water-scrue, 
as big and long as one pleaseth, in an easie and cheap way.

55. A double Water-scrue, the innermost to mount the 
water, and the outermost for it to descend more in number 
of threds, and consequently in quantity of water, though 
much shorter than the innermost scrue, by which the water 
ascendeth, a most extraordinary help for the turning of the 
scrue to make the water rise. 

56. To provide and make that all the Weights of the de- 
scending side of a Wheel shall be perpetually further from 
the Centre then those of the mounting side, and yet equal in 
number and heft to 1 the one side as the other. A most in- 
credible thing, if not seen, but tried before the late King (of 
blessed memory) 2 in the Tower, by my directions, two Ex- 
traordinary Embassadors accompanying His Majesty, and 
the Duke of Richmond and Duke Hamilton, with 3 most 4 of 
the Court attending Him. The Wheel was 14. foot over, 
and 40. Weights of 50. pounds apiece. Sir William Bal- 
fotr? then Lieutenant of the Tower? can justifie it, with 
several others. They all saw, that no sooner these great

Weights passed the Diameter-line of the lower 1 side, but they 
hung a foot further from the Centre, nor no sooner passed 
the Diameter-line of the upper* side, but they hung a foot 
nearer. Be pleased to judge the consequence. 

57. An ebbing and flowing Water-work in two Vessels, 
into either of which the water standing at a level, if a Globe 
be cast in, instead of rising it presently ebbeth, and so re- 
maineth untill a like Globe be cast into the other Vessel, 
which the water is no sooner sensible of, but that 8 Vessel 
presently ebbeth, and the other floweth, and so continueth 
ebbing and flowing untill one or both of 4 the Globes be 
taken out, working some little effect besides its own motion, 
without the help of any man within sight or hearing : But if 
either of the Globes be taken out, with ever so swift or easie 
a motion, at the very instant the ebbing and flowing ceaseth ; 
for if during the* ebbing you take out the Globe, the water 
of that Vessel presently returneth to flow, and never ebbeth 
after, untill 6 the Globe be returned into it, and then the mo- 
tion beginneth as before.

for Carabines. 

60. A way with a Flask appropriated unto it, which will 
furnish either Pistol or Carabine with a dozen Charges in 
three minutes time, to do the whole execution of a 
dozen 2 shots, as soon as one pleaseth, proportionably. 

61. A third way, and 3 particular for Musquets, without 
taking them from their Rests to charge or prime, to a like 
execution, and as fast as the Flask, the Musquet containing 
but one Charge at a time. 

62. A way for a Harquebuss, a Crock, or Ship-musquet, 
six upon a carriage, shooting with such expedition, as 4 with- 
out danger one may charge, level, and discharge 5 them sixty 
times in a minute of an hour, two or three together.

the other, yet as swift.

ot 64. pounds weight, and 24. pounds of pouder, twenty 
times in six minutes ; so clear from danger, that after all were 
discharged, a Pound of Butter did not melt, being laid upon 
the Cannon-britch, nor the green Oile discoloured that was 
first anointed 1 and used between the Barrel thereof, and the 
Engine, having never in it nor within six foot but one 
charge at a time. 

65. A way that one man in the Cabin may govern 
the 2 whole side of Ship-musquets, to the number (if need re- 
quire) of 2. or 3000. shots. 

66. A way that against 3 several Advenues to a Fort or 
Castle, one man may charge fifty Cannons playing, and 
stopping when he pleaseth, though out of sight of the Can-

Pummel of the Saddle, so that a Common Trooper cannot 
misse to charge them with twenty or thirty bullets at a time, 
even in full career.

by 1 fire, not by drawing or sucking it upwards, for that must 
be as the philosopher calleth it, Intrc? sphceram activitatis, 
which is but at such a distance. But this way hath no 
Bounder, if the Vessels be strong enough ; for I have taken 
a piece of a whole Cannon, whereof the end was burst, and 
filled it three quarters full of water, 3 stopping and scruing 
up the* broken end; as also the Touch-hole; and making a 
constant fire under it, within 24. hours it burst and made a 
great crack : So that having a way 5 to make my Vessels, so 
that they are strengthened by the force within them, and the 
one to fill after the other. I have seen the water run 6 like a 
constant Fountaine-stream, 40. foot high ; one Vessel of water 
rarified by fire, driveth up 40.' of cold water. And a man 
that tends the work is but to turn two Cocks, that one Vessel 
of water being consumed, another begins to force and 8 refill 
with cold water, and so successively, the fire being tended 
and kept constant, which the self-same Person may likewise

a Shilling 3 , shall be capable and strong enough to bolt 
and unbolt, round about a great Chest, an hundred Bolts 
through fifty Staples, two in each, with a direct contrary mo- 
tion, and as many more from both sides and ends; and at 
the self-same time shall fasten it to a place, beyond a mans 
natural strength to take it away : and in one and the same 
turn both locketh and openeth it.

which the stranger cannot stop from running out; and be-

ing him, yet it leaveth such a mark behind it, as will discover 
him if suspected; the Escocheon 1 or 2 Lock plainly shewing

never so high seated, as well to keep them sweet, running

This work was prepared by the author for the purpose of collecting and pre- 
senting in a compact form all those recipes and so-called "trade secrets" which 
have been so extensively advertised and offered for sale. It is not by any 
means a clap-trap book, though it exposes many clap-traps. It contains a large 
amount of valuable information that cannot be readily found elsewhere, and it 
gives not only the formulae, etc., for manufacturing an immense variety of arti- 
cles, but important and trustworthy hints as to the best way of making money 
out of them. Even as a book of recipes it is worth more than its price to any- 
one who is interested in the subjects on which it treats.

The extraordinary number which has been sold of the First Part of the 
"Workshop Companion," proves conclusively that such a little work was 
needed. Having received frequent inquiries for information upon subjects 
which were not discussed in the First Part, we have had a Second Part pre 
pared for the purpose of supplying the information thus called for. The Second 
Part has been edited with the same care and thoroughness which did so much 
towards rendering Part I. a favorite with every worker. The best sources of 
knowledge have been consulted, and the more important articles have been 
confided to the hands of specialists of well-known ability. 

The two parts will also be issued in one volume, printed on extra paper, and 
handsomely bound in cloth, with gilt stamp, under the title of THE PRACTICAL

No. 15. Centre ornament for panel. 

No. 16. Corner ornament for panel. 

No. 17. Key-hole escutcheon. 

These designs we have had photo-lithographed and printed on good paper, so that 
the outlines are sharp, and the opposite sides of each design symmetrical. Common 
designs are printed from coarse wooden blocks, and are rough and unequal, to that 
it is often impossible to make good work from them. 

The series embraces over forty different pieces, and designs of equal quality cannot 
be had for less than five, ten or fifteen cents each. We offer them for twenty-five 
Cents for the set, which is an average price of only one cent and a half each. 
Mailed to any address on receipt of price.
